Countdown to a Date Calculator
How many days until a date, from today.
Good to know. Checking a countdown every morning is completely normal. We won’t tell anyone.
How it works
In plain words
Subtract today’s date from the target date on the calendar. Today doesn’t count; the target day does.
The formula
days to go = target date − today
Worked example
On 15 March 2026, Christmas Day (25 December 2026) is 285 days away: 40 weeks and 5 days.

About the countdown to a date calculator
A countdown turns a date on the calendar into something you can feel: 285 days sounds very different from "December". Use it for holidays, weddings, exams, a new job, a due date, retirement, or the end of a project.
The count starts from today in your own time zone and runs to the target date. Today is not counted, and the target day is. So if the date is tomorrow, there is 1 day to go. Children often count "sleeps", which is the same number.
Next to the total, you will see the same gap in weeks and in months, and the number of weekdays (Monday to Friday) left. The weekday count is useful for work deadlines, though it does not know about public holidays in your country. The business days calculator lets you count between any two dates.
If the date you pick is in the past, the calculator shows how many days ago it was instead.
